An electronic sphygmomanometer includes a cuff including an air bladder, a pressure sensor, an artery volume sensor, and a computation device. The computation device includes an inner pressure control section, a volume sensor signal receive section for receiving a pulse wave signal detected by the artery volume sensor, a pressure sensor signal receive section for receiving a pressure pulse wave signal superimposed on the inner pressure of the air bladder and detected by the pressure sensor, a judgment section for choosing either the pulse wave signal or the pressure pulse wave signal as a signal for calculating pulse rate of the patient during a period when the inner pressure of the air bladder is increased and/or decreased by the inner pressure control section, and a pulse rate calculation section for calculating pulse rate of the patient based on the pulse wave signal and the signal chosen by the judgment section.
